Question

Reuben deposited $2000
into an account with a 3.8% annual interest rate, compounded semiannually. Assuming that no withdrawals are made, how long will it take for the investment to grow to
$3000?

Answer 1

I don't know if he does algebra, but look for Yay Math videos on U tube. He saved me in Geometry last year. He could be a little annoying, but he is a great teacher. Hope this helps.

Answer 2

If x is the number of years, you need

(1 + .038/2)^(2x) = 3000/2000
